ABSTRACT
Rice crop (Oryza sativa L.) is the main food commodity in Indonesia and a source
of energy and carbohydrates for the community. However, rice production in
several regions including Riau Province, has decreased due to the attack of plant
disrupting organisms, especially the brown planthopper (Nilaparvata lugens Stal.)
which can cause yield losses of up to 100%. Alternative control that is more
environmentally friendly is needed, namely using vegetable insecticides from
Japanese papaya leaves. This study aims to obtain the effectiveness of the
concentration of Japanese papaya leaf extract (Cnidoscolus aconitifolius I.M.
Johnst) on the mortality of brown stem planthoppers on rice plants in the laboratory.
The research was conducted experimentally using a completely randomised design
(CRD) consisting of five treatments and four replicates. The treatments given were
concentrations of 0 g.l-1 water, 25 g.l-1 water, 50 g.l-1 water, 75 g.l-1 water, and 100
g.l-1 water of Japanese papaya leaf extract. The observation parameters consisted of
the initial time of death, lethal time 50, lethal concentration 50 and 95, daily
mortality, and total mortality. The results showed that the application of a
concentration of 50 g.l-1 water extract of Japanese papaya leaves is an effective
concentration in controlling the brown stem planthopper because it has been able
to cause total mortality of 80.00% with an initial time of death 4.50 hours after
application and lethal time 50 at 33.25 hours after application. The 50 g.l-1 water of
Japanese papaya leaf extract concentration is an effective concentration because it
has been able to cause total mortality of more than 80%.
Keywords: Biological pest control, rice crop, total mortality, vegetable insecticides
